IMPROVEMENT IN FORCE-PUMPS.

Specilication forming part of Letters Patent No. 168,907, dated-October 19, 1875; application filed I September 13, 1875.

To all whom it may concern:

Be it known that I, WILLIAM C. LIBEN- GOOD, of Bradenville, in the county of Westmoreland and State of Pennsylvania, have invented certain new and useful Improvements in Force-Pumps and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the pistons may be made of Wood or iron, and

have a suitable slotted opening, c, made vertically down through their tops to receive theends of the piston-rods d, and have a larger circular opening, g, through their sides, and a vertical opening, h., through the lower ends, through which the water falls into the cylinder as the pistons are raised upward, and in grooves 'i around the lower ends are placed suitable packing, in the usual manner. As the pistons descend the valves close upward, and force the water from the cylinders through the passages j and valves l up` into the stock m through the discharge-pipe n, which pipe is connected to they reservoir o. Connected to the top of the stock by means of a pipe, s, is the reservoir, which consists of an enlarged ycircular chamber, the top of which is closed by a vertically-adjustable valve, t, that is weighted down upon its top by a weight, fv. As the water will .be forced by the pistons in to the reservoir sufficiently fast to rise above the discharge-pipe, this weighted valve bears down upon the water with suflicient pressure to cause it to llow out in a constant steady stream. This valve takes the place of the ordinary air-chamber, is cheaper, and presents muchV better results. The ends of the pistonrods d are pivoted at their tops to a walkinglever, l, that is made to vibrate up and down by the rods 2, that have their upper ends attached to the cranks or eccentrics 3 o n the ends of the shaft, to which the spur-wheel 4 is secured. The wheel 4 is operated 'by the wheel 5, to which the crank 6 is secured, the said Wheel 5 being made larger or smaller in proportion to the speed or power desired.

The whole upper portion of the pump is inclosed in a frame-Work of any suitable form or description.

Having thus described my invention, I claim- 1. The combination of the reservoir o, valve t, and .weight fv, substantially as set forth.

2. The combination of a suitable operating mechanism, pistons, cylinders, block a, and stock m with the reservoir o, valve t, and Weight t, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 1st day of September, 1875.
